wood: log-sawing patterns

Basic log-sawing patterns

Live and cant sawing may be done with a frame saw for simultaneous sawing. In cant sawing, two slabs on opposite sides of the log are first removed, producing a cant for the frame saw. Sawing for grade, done with a band saw, involves turning the log after each cut according to revealed wood quality. Sawing for radial grain enhances the figure of some species and reduces distortions due to shrinkage and swelling; the lumber so produced is sometimes called quartersawn, especially when the logs are quartered before being sawn into boards.
